Does anything like a colision plane / overlap exist?

[usa423]

What I mean is like the way a plane only can be seen from one side, a collision that only exist one way?

No in engine single direction collider but it can be done with logic

Jumping Through Platforms in UE4 Blueprints (Super Mario mechanic!)

You could also do a normalized dot product of the characters velocity and a direction then use the AcosD node to check the angle between the characters velocity and the other vector. Then you could see it the character is going in the good or bad direction relative to the other object and make decisions based on that.

Many of the Infinite-Blade assets exhibit this exact behavior which can be extremely annoying actually.

So, yes its possible… You could study some of those IB packs to see how they work (over-optimizing)…

Also, look into the 2-sided / double-sided geometry options in the static-mesh editor / material editor.

Thanks for the link, that was an excellent explanation for the phased platforms.

Don’t know those packs but will check into it. And the double sided geometry options sounds promising. Thanks for the info.
